I have been mining data for Disney Heroes: Battle Mode for several months now and within the assets folder was a collection of *.tab files which I could easily view using any text editor. Inside are tab separated values.

In a recent patch they have changed the extension to *.tabb which appears to be some sort of binary file or it has been encrypted?

At any rate, I can no longer view the contents of these files. Below is a side-by-side file size compare

Has anyone encountered this file extension before? If so, how can you decode the contents? Or what steps would I need to take to convert the file? Thanks in advance
